DGM-03

Digital CO 2
Gehaltemeter
General information
For a constant quality and taste of all sorts of
carbonated drinks, the critical parameter is the
content of the dissolved CO 2
(carbon dioxide) in
the liquid.
That is why it is common for breweries and the
soft drink industry to frequently measure the
CO 2
content during production. The portable
Digital CO 2
Gehaltemeter, type DGM- 03,
enables a fast and accurate determination of
the CO 2
content in beer and carbonated drinks,
either directly sampled during production (for
example from tanks and pipes) or after
production (for example from kegs).
Principle of operation
During sampling of the beverage, the liquid
flows through the instrument. By closing the
lever a measurement cycle starts up, creating
an electrolysis followed by pressure and
temperature measurement and electronical
calculating of the CO 2
content, which is
consecutively displayed. Within only four steps
an accurate, traceable CO 2
content can be
determinated:
- Connect the instrument to the sampling point,
- Pull the lever to allow a sample flow,
- Depress the lever to start a measurement,
- Read the displayed CO 2
content.
